This thread has mentioned that it was unacceptable for the interviewer to walk out without saying why they were leaving, or even saying goodbye and thanking you for your time.
While that was an enormous red flag, so is that they had laughed in your face about your choice for a favorite language. That person was extremely rude to you and that behavior was accepted by their co-workers.
While wanting to end that interview right on the spot is a natural reaction, I would have kept going. Depending on the size of the your market, you could get tagged as that person that bailed in the middle of the interview. Depending on how the rest of the interview went, you could be direct and ask about that interviewer and if that was indicative of the company culture.
